[0051] Embodiment 1. Refer to Figures 1 to 4 , which is the first embodiment of the present invention, and a sand washer with water circulation utilization is proposed.

[0052] In this embodiment, the sand washer specifically includes a frame 1, a stone washing tank body 2, a rotating shaft 6, a sedimentation tank 8, and a return water pump body 10; the return water pump body 10 can be selected as a water pump in the prior art; the stone washing tank body 2 is integrally arranged at an angle with the ground, and the feeding port of the cleaning tank 3 is located at the end with a lower height; during use, the material to be cleaned is placed into the cleaning tank 3, and an external force is applied to drive the rotating shaft 6 to rotate. The rotating shaft 6 drives the blades 7 to rotate, and the rotation of the blades 7 will drive the material to be cleaned to move in an obliquely upward direction; clear water enters the cleaning tank 3 from the water inlet hole 4 at a certain speed to wash the material in the cleaning tank 3. The washed soil and other impurities are discharged into the sedimentation tank 8 through the sewage discharge hole 5. The clear water that can be reused is obtained through the sedimentation in the sedimentation tank 8. With the help of the return water pump body 10, the clear water is pumped out of the sedimentation tank 8 and supplied to the water inlet hole 4 to complete the recycling of the cleaning water, reduce the water consumption during material cleaning, reduce costs, and improve the utilization rate of resources.

[0053] Embodiment 2. Refer to Figures 1 to 4 , which is the second embodiment of the present invention. On the basis of Embodiment 1, in this embodiment, further, the numbers of the water inlet hole 4 and the sewage discharge hole 5 are limited to several; they are distributed at intervals in the form of rows and columns in the cleaning tank 3; a pressure booster 11, a debris collection member 12, and a clear and sewage pump 13 are also added. The pressure booster 11 can be selected as a device in the prior art that can pressurize liquid water. The pressure of the water entering the cleaning tank 3 is increased through the pressure booster 11, and the material is washed by the water pressure to improve the cleaning effect; water enters through several water inlet holes 4 to increase the cleaning range of the cleaning tank 3; with the help of several sewage discharge holes 5, the discharge efficiency of soil and other impurities is improved, avoiding blockage in the cleaning tank 3 and reducing the cleaning effect; the washed soil impurities are collected by the debris collection member 12, and the collected impurities and sewage are transported to the sedimentation tank 8 for sedimentation and filtration; when the equipment stops running, the clear and sewage pump 13 is started. The clear and sewage pump 13 can be selected as a water pump in the prior art. The clear and sewage pump 13 is located at the end with a higher height of the debris collection member 12. After the clear and sewage pump 13 is started, clear water is output to wash the internal cavity of the debris collection member 12, avoiding the retention of impurities in the debris collection member 12 and incomplete cleaning, reducing the rust phenomenon in the internal cavity of the debris collection member 12, and improving the service life of the equipment.

[0054] Embodiment 3. Refer to Figures 1 to 4 , which is the third embodiment of the present invention. On the basis of Embodiment 1, in this embodiment, further, a spacer 14 and a filter screen 16 are added. In this embodiment, the number of intermediate partitions is preferably two, and the two partition plates divide the sedimentation tank 8 into three parts; during use, the collected sewage and soil enter the sedimentation tank 8. The lower end of the sedimentation tank 8 is provided with a water inlet. The sewage enters the sedimentation tank 8 from the water inlet and is filtered successively through the two filter screens 16, improving the filtering effect of the sewage. At the same time, a water inlet pipe is provided at each water passing hole 15 to achieve low inlet and high outlet of the sewage and improve the sedimentation efficiency.

[0055] Example 4. Refer to Figures 1 to 3 , which is the fourth embodiment of the present utility model. On the basis of Embodiment 1, in this embodiment, a buffer tank body 17 is further added. The buffer tank body 17 collects and temporarily stores the clear water in the sedimentation tank 8, improves the emergency response ability of the cleaning water, realizes the circulation of the cleaning water, reduces the sedimentation pressure of the sedimentation tank 8, and avoids the sewage in the sedimentation tank 8 from being pumped by the return water pump body 10 when the sewage sedimentation is incomplete.

[0056] Example 5. Refer to Figures 1 to 6, which is the fifth embodiment of the present utility model. On the basis of Embodiment 1, in this embodiment, a floating removal unit 18, a hanging frame 25, a suspension rod 26, a rotation drive 27 and a lifting drive 28 are further added; among them, the floating removal unit 18 specifically includes a vertical rod 19, a slider 20, a cross bar 21, a first limiting rod 22 and a second limiting rod 23; during use, since there are inevitably some impurities with small density and large volume in the sand and stone materials, such impurities will float in the cleaning tank 3 and are not convenient to be discharged through the sewage discharge hole 5. At this time, the lifting drive 28 is started. The lifting drive 28 can be a device that can provide linear drive in the prior art, such as a hydraulic cylinder; the hanging frame 25 is driven by the lifting drive 28 to move downward close to the cleaning tank 3, and the hanging frame 25 stops moving after descending to a preset position; at this time, the rotation drive 27 is started. The rotation drive 27 can be an electric drive motor in the prior art. The power output by the rotation drive 27 drives the suspension rod 26 to rotate above the cleaning tank 3; the suspension rod 26 drives the vertical rod 19 to move synchronously. At this time, the vertical rod 19 is above the cleaning tank 3 and above the sewage in the cleaning tank 3; then the lifting drive 28 is started, and the lifting drive 28 drives the hanging frame 25, the suspension rod 26 and the vertical rod 19 to move downward a certain distance and then stop moving. At this time, the lower end of the vertical rod 19 extends into the sewage in the cleaning tank 3; a pneumatic rod is built in the vertical rod 19, and the pneumatic rod drives the slider 20 and the cross bar 21 to slide downward together; before the cross bar 21 slides downward, the arc guide 24 is in contact with the first limiting rod 22. With the guidance of the arc edge, the cross bar 21 starts to rotate on the slider 20. With the sliding of the slider 20, the cross bar 21 realizes both sliding and rotation, and the cross bar 21 gradually changes from a vertical state to a horizontal state. When the slider 20 slides to the lowest position, it contacts the first limiting rod 22, and the first limiting rod 22 is used to prevent the slider 20 from separating from the vertical rod 19. At this time, the cross bar 21 is in a horizontal state; the suspended impurities in the cleaning tank 3 are above the cross bar 21. Then the lifting drive 28 outputs an upward driving force, and the hanging frame 25, the suspension rod 26, the vertical rod 19 and the cross bar 21 move upward a certain distance and then stop moving. During the movement, several cross bars 21 lift the suspended impurities, and the arc edge can prevent the suspended impurities from falling off the cross bar 21; then the rotation drive 27 starts to transmit power to drive the suspension rod 26 to rotate away from the cleaning tank 3 to the suspended impurity collection place (not shown in the figure), and then the pneumatic rod slides upward and drives the slider 20 and the cross bar 21 to move upward synchronously. At this time, the cross bar 21 gradually approaches and is in extrusion contact with the second limiting rod 23. With the extrusion of the second limiting rod 23, the cross bar 21 rotates toward the first limiting rod 22 until the slider 20 moves to the highest position, and the cross bar 21 changes from a horizontal state to a vertical state, and the arc edge is in contact with the first limiting rod 22. As the cross bar 21 changes from a horizontal state to a vertical state, the suspended impurities fall to the impurity collection place, completing the collection and cleaning of the suspended impurities.The above process operates in a regular cycle to prevent excessive accumulation of suspended impurities.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
